Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, and in particular to a surface treatment device for stainless steel fittings. Background Technology

[0002] In the production and manufacturing process of stainless steel fittings, in order to improve their corrosion resistance, wear resistance and aesthetics, it is usually necessary to treat their surface. Common surface treatment methods include grinding, electroplating, chemical plating and spraying. There are various stainless steel fitting surface spraying devices on the market. Common ones include manual spray guns with simple fixtures, as well as some more automated assembly line spraying equipment.

[0003] For example, Chinese patent CN221230841U discloses a stainless steel pipe spraying equipment, which includes a working plate. Support legs are fixed at the four corners of the bottom of the working plate, and two U-shaped fixing plates are fixed on the top surface at intervals. Fixed rollers are rotatably connected to the inner sides of the two U-shaped fixing plates, and motors for driving the fixed rollers to rotate are installed at the front ends of the two U-shaped fixing plates.

[0004] In existing technologies, stainless steel parts are typically coated using manual spray guns. However, due to variations in worker skill and stability, the spraying force, angle, and moving speed can change, resulting in inconsistent coating thickness on the stainless steel parts, with some areas being too thick or too thin. While assembly line spraying equipment can ensure a certain level of production efficiency, the fixed position of the spray gun or the limited rotation angle of the stainless steel parts makes it difficult to guarantee uniform coating coverage on all parts. To address these issues, a surface treatment device for stainless steel parts is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a surface treatment device for stainless steel fittings.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a surface treatment device for stainless steel fittings, comprising a spraying mechanism, a spraying assembly, and a moving mechanism. The bottom of the moving mechanism is provided with a flipping mechanism. The flipping mechanism includes an arc-shaped plate, a rotating rod, an electric push rod, a motor, a fixed gear, a connecting frame, a clamp, a connecting rod, a sliding rod, and a fixed disk. One end of the fixed gear is fixedly installed to one side of the fixed disk. The output end of the motor is fixedly connected to one end of the rotating rod, and one end of the rotating rod passes through the fixed disk and is fixedly connected to one side of the arc-shaped plate. Protective plates are symmetrically welded to both sides of the shaped plate. The outer side of the connecting frame is welded to the outer side of the arc-shaped plate. A movable gear is rotatably connected to one end of the connecting frame. The outer edge of the movable gear meshes with the outer edge of the fixed gear. One end of the movable gear passes through the connecting frame and is fixedly connected to a bevel gear. A connecting rod is rotatably installed on one end of the arc-shaped plate, and an electric push rod is fixedly installed on the other end of the arc-shaped plate. One end of the connecting rod is fixedly connected to one end of a bevel gear. A movable plate is fixedly connected to one end of the electric push rod. One end of the clamp is rotatably installed on one side of the movable plate.

[0007] Preferably, one end of the sliding rod is welded to one end of the connecting rod, and the other end of the sliding rod is fixedly connected to a constant force spring.

[0008] Preferably, a sliding seat is slidably connected to the outer wall of the sliding rod, and a pressure plate is fixedly connected to one side of the sliding seat.

[0009] Preferably, the inner side of the pressure plate is fixedly connected to one end of the constant force spring, and one end of the connecting rod is symmetrically rotatably connected to two clamping arms.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, one end of the stainless steel fitting is clamped by a clamp, and the other end is clamped by a clamping arm. This allows for clamping and spraying of stainless steel fittings of different sizes, enhancing the applicability of the device. The stainless steel fitting is clamped and fixed by the clamp and clamping arm. The rotating rod and arc plate are driven by a motor to rotate, and the stainless steel fitting can rotate on its own axis as the arc plate rotates. The spraying component can spray the surface of the stainless steel fitting from all directions, eliminating the problem of uneven spraying caused by the limited rotation angle of traditional stainless steel fittings. It eliminates the need for workers to use manual spray guns to spray the stainless steel fittings, ensuring a consistent coating thickness on the surface of the stainless steel fittings and avoiding localized over-thickness or under-thickness.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a surface treatment device for stainless steel fittings, including a spraying mechanism 1, a spraying assembly 2, and a moving mechanism 3. A flipping mechanism 4 is provided at the bottom of the moving mechanism 3. The flipping mechanism 4 includes an arc-shaped plate 43, a rotating rod 45, an electric push rod 47, a motor 48, a fixed gear 49, a connecting frame 410, a clamp 413, a connecting rod 414, a sliding rod 415, and a fixed disk 421. One end of the fixed gear 49 is fixedly installed on one side of the fixed disk 421. The output end of the motor 48 is fixedly connected to one end of the rotating rod 45, and one end of the rotating rod 45 passes through the fixed disk 421 and is fixedly connected to one side of the arc-shaped plate 43. The two ends of the arc-shaped plate 43... A protective plate 44 is symmetrically welded on both sides. The outer side of the connecting frame 410 is welded to the outer side of the arc plate 43. One end of the connecting frame 410 is rotatably connected to a movable gear 42. The outer edge of the movable gear 42 meshes with the outer edge of the fixed gear 49. One end of the movable gear 42 passes through the connecting frame 410 and is fixedly connected to a bevel gear 46. One end of the arc plate 43 is rotatably mounted with a connecting rod 414, and the other end of the arc plate 43 is fixedly mounted with an electric push rod 47. One end of the connecting rod 414 is fixedly connected to one end of the bevel gear 411. One end of the electric push rod 47 is fixedly connected to a moving plate 412. One end of the clamp 413 is rotatably mounted to one side of the moving plate 412.

[0024] The specific settings and functions of this embodiment are described below: After the moving mechanism 3 moves the flipping mechanism 4 and the stainless steel parts to the position of the spraying assembly 2, it stops. The controller turns on the motor 48, the spraying mechanism 1 and the spraying assembly 2. The motor 48 drives the rotating rod 45 and the arc plate 43 to rotate, thereby driving the connecting rod 414, the stainless steel parts and the clamp 413 to rotate. When the motor 48 drives the arc plate 43 to rotate, the stainless steel parts can rotate on their own along with the arc plate 43. The spraying assembly 2 can spray the surface of the stainless steel parts in all directions.

[0025] Example 2: Figure 3 - Figure 5As shown, one end of the sliding rod 415 is welded to one end of the connecting rod 414, and the other end of the sliding rod 415 is fixedly connected to a constant force spring 418. A sliding seat 417 is slidably connected to the outer wall of the sliding rod 415. A pressure plate 419 is fixedly connected to one side of the sliding seat 417. The inner side of the pressure plate 419 is fixedly connected to one end of the constant force spring 418. Two clamping arms 416 are symmetrically rotatably connected to one end of the connecting rod 414. Two movable arms 420 are symmetrically rotatably connected to both ends of the sliding seat 417. One end of the movable arm 420 is rotatably connected to one end of the clamping arm 416. An assembly plate 41 is fixedly installed on the outer side of the fixed plate 421. The top end of the spraying mechanism 1 is fixedly connected to the bottom end of the spraying assembly 2.

[0026] The overall effect of this embodiment is that the controller controls the clamp 413 to hold one end of the stainless steel fitting, and at the same time, the controller controls the electric push rod 47 to be activated. The electric push rod 47 drives the moving plate 412, the clamp 413 and the stainless steel fitting to move, so that one end of the stainless steel fitting is in contact with and squeezed against the pressure plate 419. The sliding seat 417 moves along the sliding rod 415, thereby driving the clamping arms 416 on both sides to rotate inward. The clamping arms 416 on both sides hold one end of the stainless steel fitting. The stainless steel fitting is clamped and fixed by the cooperation of the clamp 413 and the clamping arms 416. It can clamp and spray stainless steel fittings of different sizes, enhancing the applicability of the device.

[0027] The device is used and works as follows: The device consists of a spraying mechanism 1, a spraying component 2, a moving mechanism 3, and a flipping mechanism 4. When it is necessary to spray stainless steel parts, the robotic arm first clamps the stainless steel parts and places them in the middle of the arc plate 43. One end of the stainless steel parts is located in the middle of the clamp 413. At this time, the controller controls the clamp 413 to hold one end of the stainless steel parts. At the same time, the controller controls the electric push rod 47 to be activated. The electric push rod 47 drives the moving plate 412, the clamp 413, and the stainless steel parts to move, so that one end of the stainless steel parts is in contact with and squeezes the pressure plate 419. When the stainless steel parts squeeze the pressure plate 419, the pressure plate 419 squeezes the constant force spring 418. At the same time, the sliding seat 417 moves along the sliding rod 415, thereby driving the clamping arms 416 on both sides to rotate inward. The clamping arms 416 on both sides clamp one end of the stainless steel parts. At this time, the stainless steel parts are clamped and fixed under the action of the clamp 413 and the clamping arms 416.

[0028] The moving mechanism 3 is activated, which drives the flipping mechanism 4 and stainless steel parts to the position of the spraying assembly 2 and then stops. At this time, the controller activates the motor 48, the spraying mechanism 1, and the spraying assembly 2. The motor 48 drives the rotating rod 45 and the arc plate 43 to rotate. At this time, the movable gear 42 rotates around the fixed gear 49. When the movable gear 42 drives the first bevel gear 46 to rotate, it causes the second bevel gear 411 to rotate, thereby driving the connecting rod 414, the stainless steel parts, and the clamp 413 to rotate. When the motor 48 drives the arc plate 43 to rotate, the stainless steel parts can rotate on their own axis while rotating with the arc plate 43. The spraying assembly 2 can spray the surface of the stainless steel parts from all directions (e.g., ...). Figure 1 As shown, the spraying component 2 is located directly in front of the flipping mechanism 4 to spray the stainless steel parts, which gets rid of the problem of uneven spraying caused by the limited rotation angle of the traditional stainless steel parts. It eliminates the need for workers to use manual spray guns to spray the stainless steel parts, ensuring that the coating thickness on the surface of the stainless steel parts is consistent and avoiding local over-thickness or under-thickness. In addition, the stainless steel parts are clamped and fixed by the cooperation of the clamp 413 and the clamping arm 416, which can clamp and spray stainless steel parts of different sizes, enhancing the applicability of the device.

[0029] After the stainless steel fittings are coated, the moving mechanism 3 drives the flipping mechanism 4 and the stainless steel fittings to move to the next process. By adding protective plates 44 on both sides of the arc plate 43, the combination of the arc plate 43 and the protective plate 44 can achieve a certain protective effect. The coating that is not attached to the surface of the stainless steel fittings can slide down along the protective plate 44, making it convenient to collect the coating.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
